The Astrophysical JournalFluorescence line diagnostics of the Fe K α line at ∼6.4 keV observed in both solar and stellar flares can constrain the latitude and size of the flare loop, even in the absence of imaging observations. However, they are hampered by the unresolved origin

Optical & X-ray Studies of Ultraluminous X-ray Sources [PDF]
, 2009 Ultraluminous X-ray Sources (ULXs) are point like X-ray sources situated external to the nucleus of their host galaxy, with inferred X-ray luminosities in excess of 10^{39} erg s^{−1} .

Li production by stellar flares in young open clusters
, 2008 The correlation observed between the Li abundance and surface activity of young cool stars is not explained by current stellar evolution models. We study the possibility that this correlation arises from significant in situ production of Li by solar-like

X-ray Super-Flares From Pre-Main Sequence Stars: Flare Energetics, Frequency, and Loop Geometry
, 2021 Solar-type stars exhibit their highest levels of magnetic activity during early convective pre-main sequence (PMS) phase of evolution. The most powerful PMS flares, super-flares (SFs), have total energies 1034-1038 erg.

Decomposition of the X-ray waveform of soft gamma-ray repeaters during giant flares
, 2010 We have analyzed the observations of SGR 1806-20 and SGR 1900+ 14 during giant flares made with the Rossi X-ray Timing Explorer. We have studied the pulsating tail after the initial spike and decomposed the pulse waveform into separate components of sub ...

Orthodontic treatment in periodontitis patients
Periodontology 2000, EarlyView.Abstract This paper examines the complex interplay between orthodontic intervention and periodontal conditions in individuals with periodontitis. It outlines diagnostic and treatment approaches for adolescents and adults, considering their distinct periodontal, dental, and behavioral needs.
